Quizplus · Accepted Answer

Epinephrine is often added to local anesthetics to cause vasoconstriction, which limits blood flow to the area and can prolong the effects of the medication. This can be particularly useful in procedures where bleeding is a concern, such as dental work or minor surgeries. However, it should be noted that epinephrine should not be used in certain patients, such as those with certain cardiac conditions or allergies to epinephrine.
